# The jit is a special-case, using sphinx rather than texinfo.

#
# sphinx is packaged in Fedora and EPEL 6 within "python-sphinx",
# and in openSUSE within "python-Sphinx".
#
# For EPEL6, python-sphinx is sphinx 0.6.6, which is missing various
# directives (e.g. ":c:macro:"), so we need the variant
# python-sphinx10 package. The latter installs its executable as
# /usr/bin/sphinx-1.0-build
# so we need to override SPHINXBUILD with this when invoking "make".
